The scalp environment

Most hair routines are a single nightly product, and the scalp it goes onto is treated as scenery.

But the condition of the scalp surface is something you can see and feel. Dead surface cells build up. Sebum collects. Styling product lingers. Some areas run dry. A scalp carrying all that is not a clean surface to apply a serum to.

That is the whole premise, and it is a cosmetic one. It is not a claim that the scalp blocks the serum, or that the Scalp Reset Serum helps anything get anywhere. The serum is applied to the scalp surface either way. The premise is preparation: a serum applied to a clean, balanced scalp is applied to the surface it was formulated for.

So on the Advanced Protocol, once or twice a week, the surface is put in order before the nightly serum goes on. Buildup lifted, excess oil cleared, the surface rebalanced. Then the Follicular Serum, every night, for 12 weeks. Most people notice the difference first as a scalp that feels cleaner and more comfortable, and roots that look fresher between washes.

The study we cite assessed the active, and no measured figure is attached to the Scalp Reset Serum. Note 14 describes how the two products run together.
